To all 1071/0711, it wmf/ zy concern.-

Be it known that I, CHARLES P. FREE- sTATE, a citizen of the United States of America, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Chung-Machines, of which the following is a speciiioation.

In the manufacture of cloth for windowshades the cloth is glued at its edges to a stretcher-frame before being sized and painted and is then allowed to dry while so stretched.

This invention has 'particular reference to machines for applying glue to such stretcherframes.

The main objects of this invention are to provide an improved form of portable machine for applying glue to the vertical face of a frame; to provide improved means for supplying a uniform rate of feed for the glue; to provide an improved system of guides which may be readily adjusted for guiding the machine along the upper or lower edge of a frame, and to provide a structure for supporting the gluing-wheel which will permit of the ready withdrawal of the wheel from the glue-receptacle for the'purpose of cleaning the various parts. These objects are accomplished by the device shown in the accompanying drawings, in which Figure 1 represents a transverse section of a frame for stretching shade-cloth and showing a portable gluing-machine constructed according to this invention in two different positions with respect to the frame. The upper part of the view represents the gluingmachine in section, with its guide-rollers in position for guiding the machine along the upper bar of the frame. The lower part of the view shows a side elevation of the machine with its guide-rollers in position for guiding the machine along the lower bar. Fig. 2 is a front elevation of the gluing-machine. Fig. 3 is a front elevation of the gluing-wheel removed from the machine. Fig. 4 is a side elevation showing a modiiied arrangement of the gluing-wheel.

In the construction shown in the drawings the main body of the machine consists of a tank 1, which is hermetically closed at its upper part and communicates, through a small opening 2, with an open receptacle or trough 3, which is rigidly connected with the tank 1 and located on the front side thereof. The tank 1 is provided with handles 4 and 5, so

that it may be readily carried from place to place.

The machine shown in the drawings is particularly designed for applying glue along the edges of the top bars 6 and bottom bars 7 of a shade-cloth stretcher such as is illustrated in Fig. 1. In the usual construction of these frames long horizontal bars 6 and 7 are connected by a plurality of adjustable cross-bars 8 and are suspended from a suitable trolley, which is not shown in the drawings, so as to hang in a vertical plane in the position illustrated. The tank has rigidly mounted thereon two pairs of arms 9, having horizontally-disposed guide-rollers 10 journaled at their ends. The upper pair of guide-rollers 10 are suitably located for engaging the front face of the u per bar 6 of the frame, and the lower pair o guide-rollers 10 are suitably located for engaging the front face of the lower bar 7 when the machine is in the two positions shown in Fig. 1. A second set of guiderollers 11 are loosely journaled at the forward ends of a pair of horizontally-disposed shafts or arms 12. rIhese arms 12 are mounted upon slides 13, which are vertically disposed and slidable in the guides 14. The guides 14 also serve as stops for engaging the bosses 15 on the slides 13 and limiting their movement to the two positions shown in Fig. 1. When the shafts 12 are in their uppermost position, the guide-rollers 11 will bein osition for riding upon the upper edge of the ower bar 7 of the frame when applying glue to the front face of said bar. Similarly when the shafts 12 are in their lowest position the guide-rollers 1 1 will be in position for bearing on the lower edge of the upper bar 6.

The tank 1 is provided with an opening 13 in its bottom, which is closed by a cover 14 and gasket 15. The cover is forced down upon its seat by means of the screw 16, which extends through a threaded aperture in the cross-bar 17. bar 17 are loosely seated in suitable holes in the lugs 18. When the device is to be iilled, it is inverted and the cover 14 is removed, so as to permit the liquid to be poured into the opening 13. I/Vhen thev cover is fastened down, the device is returned to its upright position, and air will enter the orifice 2 until the upper edge of said orifice is submerged below the level of the liquid in the receptacle 3. The remaining liquid in the tank 1 will be supported by the vacuum in the space 19 The ends of the cross- IOO IOS

tate on its axis.

at the top, and no further liquid will enter the receptacle 8 until the level of the liquid has been lowered so as to admit air at the orifice 2.

The gluing-wheel 20 is journaled on a spring clip or frame 21. This wheel is conical and so located that a portion of its periphery dips below the level of the liquid in the receptacle 3, while the upper portion thereof extends above the rim of the receptacle 3 into position for engaging a vertical surface above said rim.

The frame 21 preferably consists of two side members connected by a cross-bar 22., upon which the wheel 20 is mounted. The side members are of spring-steel and are bent so as to bear upon the face of the tanli at the points 23 and 24 and then to extend forward and upward to form the springtongues 25 in front of the wheel 20. These tongues are offset at 26 at their upper ends to engage the bead at the rim of the receptacle 3, as shown in Fig. 1. Then the frame 21 is pressed down into position in the tank D 3, the offset ends of the tongues 25 spring under the bead and rigidly hold the wheel 20 in position, while permitting' it to freely ro- A pair of idle rollers 27 bear upon the periphery of the wheel 2O at each side and insure an even distribution of the glue upon the periphery of said wheel when the wheel is rotating in either direction. The rollers 27 are carried by arms 28, which are preferably flat and extend close to the periphery of said rollers, so as to act as scrapers for removing the glue from the surface of said rollers.

In the modified form shown in Fig. 4 the glue is taken up by a wheel 29, which dips below the surface of the liquid and carries liquid to the periphery of the gluing-wheel 20. In this case the frame 21 is provided with a cross-bar 22 for each wheel.

In cases where the bars 6 of the frames are of a standard size it is preferred to provide one or more additional guide-rollers 30, carried by a frame 31, extending forward from the top of the tank 1 to support the weight of the machine when applying glue to the upper bar 6.

The operation of the device shown is as follows: To apply glue to the upper bar 6 of the gluing-frame, the slides 13 are pushed down until stopped by the lower guide 14. The machine is then held in the position shown in the upper part of Fig. 1 while the operator walks along throughout the length of the bar 6. l/Vhen the slides are in this position, the guiding-rollers 11 are in suitable position to engage the lower edge of the bar 6 and bring the rollers 20 into proper position for applying a strip of glue along the face of said bar near its lower edge. The upper guide-rollers 10 engage the face of the bar 6 and insure that the periphery of the wheel 2O lies iiat against the face of the bar 6. IVhile applying glue to the upper bar 6 the weight of the machine is carried by the idle roller 30. In applying glue to the lower bar 7 of the stretcher-frame the guide-rollers 11 are shifted to their upper position and then rest up on the top of the bar 7 and supporting the weight of the machine while the operator walks along. The lower guiderollers 10 are in this case brought into service. To remove the roller 2O from the receptacle 3 for the purpose of cleaning said roller and receptacle, the operator presses inward on the ends of the spring-tongues 25, so as to release the offset 26 from engagement with the bead on the receptacle. The frame 21 may now be lifted upwardly out of said receptacle.

In the modified form the lower roller feeds the glue to the gluing-roller, and the wiping action due to the conical form of the rollers insures a uniform distribution of the glue.
